Is Menstruation Obsolete?, by Elsimar M. Coutinho, MD, PhD (Oxford University Press, $24).

Synopsis: A woman’s period is a recent phenomenon. In early times women were typically either pregnant, lactating, or dead. Animals generally don’t menstruate, except for a few apes and “some bats and shrews.” End it through medication, or surgery.

Representative quote: “Hysterectomy can be considered as a solution for serious complications.”

Noteworthy flaw: Brazilian author uses astonishingly high rate of incest pregnancy among 10- and 11-year-olds in Brazil as argument to chemically delay puberty so “the young girl may be less likely to be targeted and victimized.”

This Is Your Time: Make Every Moment Count, by Michael W. Smith (Thomas Nelson Publishers, $12.99).

Synopsis: Christian singer Smith performs at the Columbine High School memorial and is inspired by Cassie Bernall’s death to write a song he is fond of.

Representative quote: “Somehow, God had translated a young woman’s heart into a song that could inspire a generation.”

Noteworthy flaw: After spending two pages on the ant problem at his country home, Smith concludes, “While bugs are a nuisance, they’re not the end of the world. Cassie’s martyrdom calls us back to the things that matter.”

So You Want to Be a Stay-At-Home Mom, by Cheryl Gochnauer (InterVarsity Press, $9.99).

Synopsis: You aren’t earning that much anyway, not when you subtract day care and fancy lunches. Better to quit your job and watch the kids. Don’t worry, your education won’t go to waste.

Representative quote: “Cheryl uses her piano background to nurture her children’s musical talents; Jennifer’s English degree comes in handy as she volunteers at her son’s school library and helps check his written essays.”

Noteworthy flaw: Suggests that stay-at-home moms live longer and have “greater physical and emotional resources to deal with marital demands”–aka sex –due to afternoon naps.
